A computer user can open without a prompt a digitally signed project from a trusted publisher. Otherwise, the application blocks opening signed projects from untrusted publishers as well as unsigned projects.
A computer user can open without a prompt a digitally signed project from a trusted publisher. In addition, you can also designate the publisher of a signed project as trusted so their projects will open without a prompt in the future. Unsigned projects are always prompted with a reminder that the file may contain potentially harmful code, but users can elect to open them anyway.
A computer user can open an unsigned project without a prompt. When users make a Low security setting, they're reminded that they aren't protected from potentially unsafe macros.
"If you've used Access 2003, you've probably seen several security warning messages - Access 2003 cares about your security. An important part of Access 2003 security is digitally signing your code. As Rick Dobson shows, you can do it, but preparing for digital signing is critical.
A digital signature acts like shrink-wrap on your project: Clients know that they're getting a copy directly from you that no one else modified. Clients will also know that they're working with "your" code and not any version of it modified by a third party. As computing moves forward into a "security conscious" era, learning how to acquire and use a digital certificate is also important for interfacing with organizations that adopt policies of only running digitally signed Access 2003 projects: Your users may refuse to accept software from you that isn't shrink-wrapped."
